Special Issue Information

Dear Colleagues,

We are pleased to invite you submit a paper to this new Special Issue of Buildings entitled “Applications of Phase Change Materials (PCMs) in Buildings”.

In buildings, PCMs are used to store and release thermal energy during the heating and cooling process. By incorporating PCMs into building materials such as walls, floors, and ceilings, the material in question can absorb excess heat during the day and release it at night when temperatures are cooler. This helps to reduce the energy consumption of a building and improve its overall efficiency.

The importance of PCMs in buildings lies in their ability to reduce energy consumption and improve thermal comfort. By using PCMs, buildings can reduce their reliance on traditional heating and cooling systems, which can be expensive and environmentally detrimental. PCMs can also help to reduce peak energy demand and improve the stability of the electricity grid.

Overall, PCMs constitute an important technology for improving the energy efficiency and sustainability of buildings. As the demand for green buildings and sustainable design continues to grow, PCMs are likely to become an increasingly important component of building design and construction.

This Special Issue aims to compile and present recent research progress made in the field of PCMs towards reducing energy consumption and improving comfort in buildings.

We invite authors to submit original research articles and reviews, particularly those that explore the applications of PCMs in building construction and energy management, including thermal energy storage, insulation, smart windows, thermal collectors, heat exchangers and so on.

I/We look forward to receiving your contributions.

Abstract

This paper determines the best design parameters and uses conditions of lightweight aggregate concrete panels containing microencapsulated phase change materials (MPCM-LWAC panels). The main work of this paper includes the followings: (1) The fundamental properties (dry density, thermal conductivity, and specific heat capacity) of MPCM-LWAC were researched to reveal the effect of MPCM dosage on these properties. (2) A model test was carried out to quantify the effect of MPCM dosage on the thermal response of the MPCM-LWAC panel exposed to realistic climate conditions. (3) The numerical simulation was conducted to investigate the effect of MPCM dosage, panel thickness, and outdoor temperature conditions on the thermal response of the MPCM-LWAC panel, which helps to determine its optimum design parameters and use condition. The results showed that the incorporation of MPCM results in lower dry density and thermal conductivity of MPCM-LWAC but higher specific heat capacity. The more MPCM dosage in the MPCM-LWAC panel with a thickness of 35 mm, the lower the energy demand to keep a comfortable interior temperature. Most notably, when the panel thickness exceeds 105 mm, the MPCM-LWAC panel with 5% MPCM only delays the peak temperature. Moreover, the optimal use condition for MPCM-LWAC panels is an average outdoor temperature of 25 °C, which makes the energy demand attain a minimum. Full article

Abstract

The use of phase change materials (PCMs) has become an increasingly common way to reduce a building’s energy usage when added to the building envelope. This developing technology has demonstrated improvements in thermal comfort and energy efficiency, making it a viable building energy solution. The current study intends to provide a comprehensive review of the published studies on the utilization of PCMs in various constructions of energy-efficient roofs, walls, and ceilings. The research question holds massive potential to unlock pioneering solutions for maximizing the usefulness of PCMs in reducing cooling demands, especially in challenging high-temperature environments. Several issues with PCMs have been revealed, the most significant of which is their reduced effectiveness during the day due to high summer temperatures, preventing them from crystallizing at night. However, this review investigates how PCMs can delay the peak temperature time, reducing the number of hours during which the indoor temperature exceeds the thermal comfort range. Additionally, the utilization of PCMs can improve the building’s energy efficiency by mitigating the need for cooling systems during peak hours. Thus, selecting the right PCM for high temperatures is both critical and challenging. Insulation density, specific heat, and thermal conductivity all play a role in heat transfer under extreme conditions. This study introduces several quantification techniques and paves the way for future advancements to accommodate practical and technical solutions related to PCM usage in building materials.
